Kate auto renderer for HTML exports needs update

[Lawrence-Pet]

I couldn't get the auto renderer work with the generated snippets in the HTML due to issues with the integrity values. I updated the values in the header to:

<!-- KaTeX stylesheet -->

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/katex@0.16.9/dist/katex.min.css" integrity="sha384-n8MVd4RsNIU0tAv4ct0nTaAbDJwPJzDEaqSD1odI+WdtXRGWt2kTvGFasHpSy3SV" crossorigin="anonymous">

<!-- The loading of KaTeX is deferred to speed up page rendering -->
<script defer src="https://cdn.jsdelivr.net/npm/katex@0.16.9/dist/katex.min.js" integrity="sha384-XjKyOOlGwcjNTAIQHIpgOno0Hl1YQqzUOEleOLALmuqehneUG+vnGctmUb0ZY0l8" crossorigin="anonymous"></script>

<!-- To automatically render math in text elements, include the auto-render extension: -->
<script defer src="https://cdn.jsdelivr.net/npm/katex@0.16.9/dist/contrib/auto-render.min.js" integrity="sha384-+VBxd3r6XgURycqtZ117nYw44OOcIax56Z4dCRWbxyPt0Koah1uHoK0o4+/RRE05" crossorigin="anonymous"
	onload="renderMathInElement(document.body);"></script>

<!-- Optional autorender configuration -->
<script>
	document.addEventListener("DOMContentLoaded", function () {
		renderMathInElement(document.body, {
			delimiters: [
				{left: "$$", right: "$$", display: true},
				{left: "\\[", right: "\\]", display: true},
				{left: "$", right: "$", display: false},
				{left: "\\(", right: "\\)", display: false}
			]
		});
	});
</script>

This references the latest version of Katex which might not be suitable, but it does work.

I have to little knowledge of js and how the exportation works to propose a solution, but the current exporter to html provides scripts with broken integrity values which does not render Katex.
